An automatic supply and loading device for container blanks such as gable top containers including storage magazines for storing therein the blanks in a flat collapsed form at a location away from the main magazines from which the blanks are individually transferred to later processes in a liquid food charging machine. A robot with a pair of grasping claws is provided between the main magazines and the storage magazines so that the robot carries the blanks between the magazines and loads and unloads the blanks in and from the magazines. The main magazines can be inclined at the same angle as the angle of inclination of the robot for securing smooth loading and unloading of the blanks.

Automatic supply and loading device for sheet items

A cutting apparatus and opening method for a rectangular package covered with packaging material includes a platform for positioning a rectangular package. Spacing members are provided for forming a space between the packaging material and the packaged items on two mutually opposing planes of the package on the platform. A pair of cutting blades are mounted for cutting the packaging material from one edge to the other in the direction of height or width where a space is formed between the packaging material and the packaged items by the spacing members. A pair of cutting blades are also mounted for cutting the packaging material from one of the two edges other than the edges passing the starting point and the finishing point of each of the two cutting lines cut by the pair of cutting blades to the above-memtioned cutting lines. A second spacing member is provided for forming a space between the packaging material and the packaged items on the plane with two edges that pass the ends of the two cutting lines made by the pair of cutting blades. A cutting blade cuts the packaging material for connecting the two cutting lines on the above plane and a device is provided to open the packaging material from each area on the three planes provided with cutting lines.

Cutting and opening method and device for a rectangular package covered

A method and device are disclosed for raising rimpled and flattened parallelepipedic blanks to form rectangular parallelepipeds. A supply of flattened parallelepipedic blanks are rolled out in a first rolling direction through a pair of discharging rollers. Pressure is imparted on the flattened parallelepipedic blanks in a direction opposite to the first rolling direction by means of a pusher for opening the blank to nearly 180.degree. in a direction perpendicular to the rolling direction. The pusher is thereafter retracted in the first rolling direction to raise the blank to form a rectangular parallelepiped with a substantially square-shaped cross section. The formed blanks are thereafter unloaded from the device.

Method of and a device for raising flattened parallelepipedic blanks

A transport device for packaging container blanks includes a platform for positioning a package of a plurality of flattened packaging container blanks covered with packaging material disposed around the plurality of flattened packaging container blanks. A cutting device is provided for cutting the packaging material disposed around the plurality of flattened packaging container blanks to expose the flattened packaging container blanks for further processing. A main magazine is provided for stacking the plurality of bare blanks after removal of the packaging material. The main magazine supplies individual bare blanks, one at a time to a subsequent processing station. A robot includes a grasping member for grasping a predetermined number of bare blanks disposed on the platform and delivering the bare blanks to the main magazine.
